[Gl4java-development] GLJPanel Under Windows 2000

[<wj...@Th...>]

I'm a novice to GL4Java (pretty new to GL in for that matter). I tried to
run some of the GLJPanel samples, and I can't get any of them to run
successfully. I am successfully using GLCanvas.

I am trying to get the GLJPanel working on Windows. I'm using Windows 2000.
I can get create a GLContext successfully, but the native call to
gljMakeCurrent fails. I compiled all the native code and poked around in a
bit, and it seems to me that something is missing in the Windows version of
Java_gl4java_GLContext_gljMakeCurrentNative.

The line it dies on is:
if ( ret==JNI_TRUE && !disp__wglMakeCurrent(GET_USED_WINDOW(thisWin),
(HGLRC)((PointerHolder)glContext)) )


The first parameter is 0. It appears to be that dsi_win is initialized to
NULL in the jawt_create_offscreen call, and it is never set to anything
else. The only chance it would get to be changed is in jawt_lock, but since
dsi_win_created is never updated anywhere, it's initial value of 1 remains
unchanged, and dsi_win is never set. It is actually set in
gljDestroyNative, but I don't think that helps here...

This is a bit different from the X11 code though. It has this code:
if(ownwind || joffScreenRenderer==JNI_TRUE)
{
pData->dsi_win=(void *)(PointerHolder)theWindow;
pData->dsi_win_created=1;
}


So, here are some questions:
1 - Has anyone run the GLJPanel samples under Windows?
2 - How does dsi_win get updated if dsi_win_created is never changed?

Thanks in advance!
